PENNSYLVANIA, A CORPORATION OF PENNSYL- SEPARATING DEVICE.

Specification of Letters Patent. Patented B131, 13, 1917.

Application filed November 3, 1915. Serial No. 59,475.

To all whom it may concern: 7

Be it known that I, MONTGOMERY SLEETH, a citizen of the United States, and a resident of Bellevue, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Separating Devices; and I do hereby declare the follow ng to be a full, clear, and exact descriptlon thereof.

My invention pertains to separating devices, and relates. particularly to magnetic devices for separating extraneous metallic articles from cotton or the like. In the manufacture of mattresses, for instance, it is customary tobreak up and mix the bulk cotton, or similar material, intended for filling the same. In such bulk cotton, there is commonly found a quantity of forelgn metallic articles, such as nails, odd pieces of iron and the like.

It is an object of the present invention to provide a simple and easily constructed mag netic device for abstracting such foreign articles. It is another object of the invention to provide such a separating device with a simple means for effecting the final removal of the articles separated. And other and further objects of the invention will appear from the following specification taken in connection with the claims appended thereto.

One form of separating device constructed in accordance with my invention is shown, by way of example, in the accompanying drawing, and described in the following specification. It is to be understood, however, that the device may be embodied in other forms and that changes may be made in the embodiment shown and described, without exceeding the scope of the invention, as defined in the appended claims.

In the drawing:

Figure 1 is a rear elevation of a separating device constructed in accordance with my invention, showmg the same as applied to a cotton breaking and mixing machine; and t Fig. 2 is a side elevation of the same, looking from the right hand side of Fig. 1, part of the side wall ofthe breaking machine being broken away and the driving pulley omitted.

Like reference characters refer to like parts throughout the following specification The cotton breaking and mixing machine,"

to which the separating device is shown as applied, includes a frame having side walls 10 and 11, between which ismounted a 1'0- tating drum 12, over which passes a band 13, which latter is thus kept in continuous forwarding movement. The band 13 carries a plurality of pickers 1 4, which pick the cotton up in fragments from a supply hopper and carry it over to a delivery hopper, the effect being to break and mix up the cotton. Machines of substantially this character are well known in the art, and no further description of the same is, therefore, necessary here. a

, Mounted on the inside of each of the side walls 10 and 11 is a standard 15, such stand- The standards 15 are bent rearwardly at their top ends so as to terminate vertically above the axis of the drum 12. the standards is mounted a crossbar 18,

which has hangers l9 pivoted thereto at its ends beyond the standards 15-. 19 are connected together by'means of a crossbar a plurality of The hangers 20, which carries downwardly extending electromagnets 21, the cores of which pass through the cross-bar 20 and are secured thereto by means of nuts 22. As the cotton is carried over the drum 12 by the pickers 14, anything therein which may be formed of iron or steel, and any iron or steel parti- Between at their lower ends I cles, are attracted by the magnets 21 and atremaining on the cotton proceeds to" are each provided a one or the other of which notches engages the corresponding bracket 26, according as the hangers are in their operative position (Fig. 2 full lines), or in their inoperative position (Fig. 2, broken lines). When it is desired to remove the articles which have adhered to the magnets, the links 25 are lifted somewhat to clear their notches :27 from the brackets 26, and the hangers are then pulled upward, by means of the links, until the magnets '21 hang over the tray 2%, in which position they are held by engage ment of the notches 28 with the brackets 26. \Vith the hangers in this position, current is shut off from the magnets, whereupon the articles dropped into the tray 2 L which can be removed with them. In order that the vertical distances between the magnets 21 and the cotton passing thereunder may be varied to suit the requirements of any par ticular case, the hangers 19 are provided with a plurality of suspension holes for the links 25.

In order that both of the links 25 may be disengaged simultaneously, I provide a cross bar 31, the upwardly bent ends 80 of which are pivoted in brackets 27 carried by the standards 15. The points of the ends 30 engage beneath thelinks 25, so that, by rocking the cross bar 31, both links may be raised together, and their notches 28 disengaged from the brackets 26.

lhe device described above provides a very eiiicient means of removing iron and steel from cotton or the like. It is extremely simple of manufacture and can be produced at an exceptionally low cost. Furthermore its attachment to the machine requires no changes or alterations in the construction.

hat I claim as new and desire to secure by Letters Patent is ried by said cross-bar, said hangers being d1sp0sed so as normally to support sa1d cross-bar and magnets in proxlmity to sa1d .ccnveyer, a receiver carried between said standards, and means for moving said hangers to bring said electro-magnets into cooperative relation with said receiver.

2. The combination with a material conveyer, of a pair of standards disposed, one at each side of saidconveyer, a pair of hangers pivoted to said standards and capable oi vertical adjustment with respect thereto, a cross-bar carried by said hangers, electromagnets carried by said cross-bar, said hangers being disposed so as normally to support said cross-bar and magnets in proximity to said conveyer, a receiver carried between said standards, and means for moving said hangers'to bring said electro-magnets into cooperative relation with said receiver.

3. The combination with a material conveyer, of: means for separating iron or steel articles from the material to he carried by said conveyer, said separating pecans including a pair of standards disposed one at each side of said conveyer, a pair of hangers pivoted to said standards and capable of vertical adjustment with respect thereto, a crossbar carried by said hangers, electr c-magnets carried by said cross-bar, said hangers being.

disposed so as normally to support said magnets in proximity to said conveyer, a receiver, means for removably mounting said receiver on said hangers, links carried by said hangers for moving the latter to bring said magnets into cooperative relation with said receiver, and means for retaining said links in the positions in which said electromagnets are operative, and in which said electro-magnets are in cooperative relation with said receiver.

In testimony whereof, I the said lVION'D GOMERY SLnn'rrr have hereunto set my hand.
